E-liquid is simply a mixture of a few ingredients. There are two common bases that are used in mixing e-liquid. One is propylene glycol and the other is vegetable glycerin. There is much controversy about which base is the best, but it usually comes down to a personal preference. The most popular base however is propylene glycol and this is what most e-liquid is made from.
What is this propylene glycol that is being used in your e-liquid you may be wondering? If you have even been to a club, bar, music concert, or a similar venue and have seen the fog produced from a fog machine, you have seen propylene glycol in action. It is also a common food additive and has been classified by the U. S. Food and Drug Administration as "generally recognized as safe (GRAS) for use as a direct food additive.
What else is in e-liquid? The next most obvious ingredient is a flavoring. There is an almost countless number of flavors of e-liquid available. You have your tobacco blends, menthol blends, clove, fruit flavors, candy flavors, soft drink flavors, food flavors, and more. E-liquid can be made to taste like just about anything!
The remaining ingredients are usually very minor. Some have a very small percentage of alcohol or water in them. You can also have e-liquid that has a mixture of the two bases, so it may be like 50% propylene glycol and 50% vegetable glycerin.
The final and most important ingredient of course is the nicotine. E-liquid comes in many different nicotine strengths to suit each individual user. Without this ingredient, the electronic cigarette would be do smokers no good. It is the nicotine in the cigarette that the body craves, not all the other ingredients produced by tobacco smoke.
Should I Get A Propylene Glycol E-liquid or a Vegetable Glycerin E-liquid?
As I said before, it usually comes down to a personally preference. The biggest difference in the two bases mainly comes down to vapor production. Vegetable glycerine e-liquid tends to create a little bit thicker vapor than propylene glycol. However, on the downside, the vegetable glycerin tends to clog up atomizers at a quicker rate than propylene glycol.
Propylene glycol based e-liquids are much more predominant and you will generally find more flavors available with a PG base than a VG base. You can of course mix the two to get the benefits of both. A relatively common, though often hard to find blend, is 80% PG / 20% VG blend.
